Seedling troubles

They could have already been in the soil. That's what happened to me and it stunted my plants that I put in that soil. It could be something else, but you're conditions sound good and the only time it happened to me is from that situation.
Oh okay, thanks man. Would there be any reason why the gnats would stunt some of the plants and not the others? Also, how much were your plants stunted and did they have dark green leaves? Did they ever recover?
 
..:toke: Indi'-- Why do you have both LED and CFL going? Seedling want less intense light, and of course, veg' spectrum biased (blues),... they don't look cooked, but overly powerful lighting can retard growth,... also, It might be that they just plain don't like the soil,... soil should be a nice even moisture all around while the taproot develops initially... had to tell with that layer of perlite on top! If you've not see many adult fliers of gnats, then a root zone infestation of the munching larvae isn't likely,....

Hey Waira, thanks for your feedback! I had my mars hydro LED running at night and my CFLs on during the day over only the seedlings. I like to give them a lot of light initially and the CFLs are an easy solution to keeping my room at a more feasible temperature, especially during the day when my house heats up quite a bit.
I raised the seedlings up closer to the light as someone previously suggested, however I don't think the distance of the light is the issue because this has happened with the light far away as well as when the light was in proper range.
I was starting to think that it might be heat since we've had quite a few heat waves recently, and one currently just ending. But then I remembered the first of the most recent ones was germinated and planted at the same time as my Blue Amnesia XXL auto, which took off and is growing normally. Couple that with my temps only reaching about 85 and I really don't think it's heat either.
It might be that the soil is not evenly moist, as I have only been applying water to the rootzone area, but again, same thing with the Blue Amnesia XXL, so I'm not certain.
Also, that isn't perlite. It's gnat nix I picked up to keep the darned gnats at bay. It's been pretty effective at doing so but does mix with the soil a bit when you water so it isn't perfect.
Thanks again!
 
Tons of variables to deal with. A good solution would be to start seeds in rapid rooter, let sit outside or window sill.. Keep moist and plant when roots grow thru...

For sure, been racking my brain trying to figure this one out. I sort of think the one automazar is getting back to normal, its leaves arent as dark as the blue amnesia or the automazar before it, and its first true leaves are starting to spread out a bit more. I'm starting to wonder if it was just the heatwaves locally... hmm

Not sure what region U live in but I have no problem with seedlings in 90+ f temp (in the shade) of course the RH is 70-80% too. I find that it's a perfect environment for seedlings outside. Inside, 85f 50% RH w/ 90w blue/white LED. Rapid rooters seem to feed them up until the 6 node..then on to the flower box... 100% germ and seedling rate

TAKE A very small amount of garden sulfer and add to your main soil tote 30 gal. or larger and mix in , ALL ROOT PEST DEAD ON ARRIVAL , SIMPLE... ALSO LESS LIGHT. AND PH YOUR SOIL
 
layer of weak soil ,then stonger soil 4 inches down , lets the babies grow much better..
 
Hey dude,
Sorry it took me a while to get back here.

Man this is a tough one to diagnose. Id go with Wairas advice as he is the king when it comes to plant problems. Is this gnat mix safe for plants? Im guessing it is but just had to ask.
Hey man, no worries at all. Apparently the gnat nix is made from recycled glass and has no harmful chemicals. I've read other reviews and haven't seen anything negative. Also, when I had this same problem a few months ago I wasn't using the gnat nix. Thanks for the advice. I'll put some pics up tonight of how she looks now (she's growing, but extremely slowly and strangely). Maybe that will help out a bit more. Starting to think maybe it's pH being too high because I'm only using litmus papers and scared to bring it down too low. Maybe high pH and heat? But again, don't think it ever got too hot, and it stayed very humid throughout the higher temps.
